Gerald Schaefer 58ecf1f363 mon_procd: fix parsing of /proc/<pid>/stat ...

The output of /proc/<pid>/stat will show the process name in parentheses.
The parsing code in read_stat() tries to filter out the parentheses, which
will go wrong when the process name itself also contains parentheses, e.g.
in an output like this: "2421 ((sd-pam)) S 2420 2420 2420 ..."

In this case, the first closing parentheses will be taken as end marker,
and the sscanf() on the remaining string will silently fail, leaving its
values in uninitialized state and producing wrong data.

Fix this by using strrchr() instead of strchr() to find the last closing
parentheses. Also add return value checking for sscanf() and initialize the
values to 0.
